- A represents the base partor bottom frame of the machine.
- the base A is the frame upon which all the machine is assembled.
- B is the top part or frame-plane, supported on base A by columns (l C.
- base A On base A are two upright bosses or extended hubs 115, into which are inserted and preferably screwed the said columns. These columns are made in two pieces C C C C2, with couplings 1/1 made fast to columns C at 13.
- the upper portions C' C2of said columns have screw-threads cut on them at 12 and hand-wheels Y' Y2, screw-threaded inside, fitting the same to provide for raising or lowering the top part or frame-plane B to accommodate different kinds of work in process in the machine.
- the base A (see Fig. 5) has three tracks running around the same. Two, H H, are level tracks, on which run the car-wheels of cars F.
- the middle track or cam-track I is of varying height,according to the duty that it is expected to perform.
- This cam-track is preferably formed of light bar iron or steel and made removable and adjustable, so that it can be easily changed and a different oneempowering its place. Said track is held in position with suitable lneans for adjustment, and the variations of level are fashioned in accordance with the Work in hand.
- the well 31 for holding water, having a shelf 75, on which the pump O is placed for pumpingwater to the tank M on top of the machine.
- the object of the housing Q is to prevent water from escaping outside the machine while wetting and cooling the slickers.
- this housing are located the sprinkling-pipes 33, the water to same coming from the tankM on top of the machine through pipe 34.
- the supply is controlled by valve 41 as to quantity and may be shut off entirely, if desired.
- the pump is operated from the motor N by endless belt 15. In case of any surplus water accumulating in top tank M the same is returned to well 31 through overflow-pipe 117.
- the base A is supported for convenience of moving on truck-wheels 29 30, wheel 29 being the steering-wheel. There is a'provision for locomotion, which will be described later.
- On said base A are also mounted the boxes 114 1111, in which run the vertical rotary shafts D' D2.
- Shaft D2 derives rotary motion from a motorN on bracket 18, borne on column C to the right.
- This motor preferably electric, derives its motion from an outside source of electric energy, the wires from which (not shown) enter at a fuse-block or 'cut-out 38 on the side of the machine, Fig. 2, preferably inclosed in the form. of an insulated exible cable.
- bevel-pinion 21 At the foot of shaftD2 is a bevel-pinion 21,intermesh ing with bevel-gears 22 23 on the shaft of truckwheels 30.
- bevel-gears are mounted with a spline, so as to have longitudinal motion on the shaft, and are controlled by a le-A ver 19, pivoted at 20, carrying rings 133, which engagegrooved collars 132 on the said bevel-gears, by which means the gears can be shifted to the right orleft, as desired.
- the object is to give locomotion to the machine in any direction by power derived from the electric motor N.
- the handle 19 is in a perpendicular position, in which position the gears 22, 23, and 21 are not in mesh.
- the handle or lever 19 By moving this handle or lever 19 to the left gears 21 and 22 engage andthe machine takes motion and travels slowly on the floor.
- the handle By moving the handle the other way the gears 21 and 23 mesh and the machine takes motion in the opposite direction.
- the machine is governed by means of the hand-wheel 25, thev shaft 27, and the train of gearing 2S 2S 2S, controlling the hoor-wheel 29.
- the Inovement is slow and readily under control.
- the duty of the motor N is to operate the shaft D2, as above described, and this shaft communicates motion and power to the shaft D by means of the wire ropes or cables illustrated at 69 and 82.
- These wire ropes or cables have also the duty of carrying around the frame of the machine pairs of cars-viz., the motor-car E on the top frame and the slicker-car F on the bottom frame.
- These cars are attached to the cable as follows: The car F is held with clamp 74, Fig. S, and has lingers or steadyingarms S4, which when the car is on the straightway part of its course come into contact with the cable and prevent vibrations which might occur from any hitching along the track.
- the cable-wheel P has parts cut away in same at 85, which permits the clamps which hold the motor and slicker cars to pass around the wheel smoothly. it also provides for the take-up coupling 2l and the knocker or striker clamps 97 to pass in the same manner.
- the Jrop cable-wheels and lower ones are of similar'construction and have like duties to perform, with the eX- oeption of the striker-clamps.
- slickercars On the tracks H on base A run the slickercars. (Shown in detail on Sheet 4, Figs. 7 and 8.) These cars consist of a base portion F, mounted on truck-wheels 83, with means 74 for clamping the same to cable 82, and an upper portion F', supported on the base portion by means of ball-bearings S9 on a circular trackway, so as to rotate freely by means hereinafter to be described.
- This upper portion carries the slickers G, radially arranged, so as to have free, radial movement toward and from the center, while the upper portion F', which carries them, is rotating.
- the regulation of the advance and retreat is y governed by the formation of the cam-track I.
- the slickers G are slotted at 77 as a means of adjustment and held invposition by screw and washer 7 3.
- the slickers are of the shape illustrated in Figs. 15 to 18, inclusive, Sheet 3, and are preferably rounded at their edges, as shown in Fig. 16, and their duty is to slick, smooth, model, or iron the plastic glass into the required shape as they come in contact therewith. In practice they are preferably pastecovered on their contact-faces.
- slickers shown in Figs. 21 and 22 are designed for forming the bottom of a glass article, as shown at 94. They can be of any shape in the reverse that is desired to be imparted to the article of plastic glass in process of formation. This slicker is held in position by arms 93 centrally beneath the rotating slickers.
- Figs. 19 and 2O represent a means for making the same set of slickers fashion and shape the plastic glass at bottom as well as at the sides, but is adapted only for plain-bottom or straight-bottom glasswork.
- the frame-plane B also bears trackways f f,on which run the upper motor-cars E. These cars are impelled by the same power and at the same speed as bottom cars F by means of cable 69, driven from shaft D2 and passing over pulleys P. The said cars are connected to said cable by means of connecting-arms q and clamps h. They are thus designed to move synchronously with the bottom cars F and remain directly over the same. Between each top and bottom car extends the vertical connecting -rod 122, firmly attached to each car at the sides. arms 113, having at the extremities thereof the blow-iron supports or bearings U U for sustaining the blow-iron T in a vertical position during the entire circuit of the cars. This bearing U, Fig.
- Figs. 30 and 30a represent a method of constructing the end of the blow-iron so as to lit the clutch for driving the same by means of cross-pins 131. This admits of no difficulty in positively catching the spindle and driving the blow-iron.
- a clutch fr In the air-spindle is a clutch fr. This clutch has the proper shape to engage with the blow-iron.
- a ileXible washer 42 in the bottom of air-spindle clutch, which makes the blow-iron contact with the clutch air-tight.
- blow-irons T are removable, insertible, and hollow and bear on their lower ends the bulb of plastic glass to be modeled by the This rod carries horizontal IOO IIO
- This blow-iron receives rotary motion and a supply of air for expanding the glass bulb bymeans presently to be described.
- the shaft 63 extends from the upper to the lower car the vertical rotary shaft 63, whose office i-t is to impart rotary motion to the revoluble member of the slicker-car F by means of gear-wheel w', meshing into circular rack a; on the periphery of revoluble member FC
- the shaft 63 is run in trunnion-supported boxes S8, attached to both top and bottom cars, so as to be preserved at all times in alinement. It is supported upon ball-bearings.
- cam-track J is to automatically regulate the degree and time of the rising and falling of the blow-iron spindle p, which communicates with the vertical blow-iron T and supplies rotarymotion and air thereto.
- the function of the camtrack K is to automatically regulate the airpressure of the air-supply furnished to the said spindle
- the function of the camtrack L is to automatically control the rheostat-arm of the rheostat l/V, which regulates the amount of current supplied to the armature of the electric motor V.
- the said motor V, blow-iron spindle p, and rheostat WV' are all carried on theupper motor-car.
- the blowiron spindle receives its supply of air from an external source presently to be described.
- the said spindle receives its rotary motion from motor V, gears n and lo, shaft 63, and sprocket -Wheels m and Z.V
- the spindle is splined in the sprocket-wheel Z, so as to admit of rising-and-falling motion while rotating, and said sprocket-wheel Z is confined by a collar 73 and groove 72 from following the rising movement of the spindle.
- camtrack L the armature of the motor V is supplied with current from an external source through the rheostat W.
- the field-magnets of the inotor are supplied with a constant current and remain at all times charged while the The rheostat lV, when the motor-car arrives at the place where the glass is to be put into the machine, automatically turns on a limited supply of current to armature, thus at once starting the machine gradually under automatic regulated speed by means of the cam-track L and flangewheel 57, increasing the speed of the motor until the operation is completed, at which time the wheel 57 drops and the current is shut off from the motor-armature until next cycle is started upon. Second, as to cam-track K, on which runs the flange-wheel j.
- the duty of this cam-track and wheel is to admit of a discharge of air from an air-box 46, borne on the motor-car E.
- This air-box 4G receives its supply of air through a flexible pipe X and -air-pipe o, with a little surplus capacity for carrying air over what is actually required for the largest work to be done with the machine.
- the diameter of the flexible air-pipe X and pipe o determines the carrying capacity in air. From this air-box 4G the air has two paths open to it, one through chamber 46 to chamber 45 in column 61 'through the cross-holes 44 in blow-'iron airspindle to central passage 43 in center of blow-iron air-spindle, thence to plastic glass.
- this valve-spindle 37 gradually or otherwise, if desired, descends by the aotion of cam-track K and roller j, thus decreasing the size of the discharge-opening into this spindle until the air-passage is shut od entirely or to the extent desired as the required pressure may demand, depending upon the work in hand.
- This method of regulating air-pressure is positive and is capable of giving puffs or impulses, sudden or gradually increasing, as the case may require, by simply having the cam-track arranged accordingly. It can closely imitate the pressure given by a skilled glass-blower when operating difficult work, blowing same by lungpressure. This enables the air-pressure to be governed absolutely according to the work that is to be done with the machine.
- cam-track at J The duty of this camtracl; is to operate the lifting and lowering IIO of the blow-iron spindle, as beforesaid.
- the shaft Ris stationary most of the time, but receiving periodical impulses.
- it is arranged to give this shaft eight impulses for each operation or during one complete cycle of the cars. This is accomplished by the knockers 9.7, Fig. 26, striking against the extended arms 9S, by which each time they come in contact they advance the wheel one-eighth of a revolution.
- the object of this operation is to at all times have the flexible air-pipe X approximately in line with the motor-car E.
- the duty of this flexible pipe is to convey air under pressure to the motorcar from air-supply pipe 4, and also to carry electric wires to the motor on said cars by the interposition of the commutator 2, without which or some similar device the air-pipes and electric wires would become entangled while the machine was making one cycle.
- This plan admits of air being supplied to the cars under the same pressure at all times, at the same time carryingthe wires tothe moving cars without any danger of breakage or strain.
- the flexible pipes pass over a round elbow e, thereby preventing any sharp bends in them,whetherthey are in the position shown in Fig. 1 or Fig. 2.
- the airpipe X communicates with vertical air-pipe o on the motor-car and supplies air to valve 49, Figs. 27 and 28.
- the duty of this airvalve is to open as soon as the plastic glass is put into the machine and to close upon the operation being completed. This is accomplished through the striker-pin 52, which is adjustable upon the npr-ight shaft 54. This striker-pin engages with the star-wheel 51 on the air-valve shaft. This starwheel has eight arms.
- the air-valve has four openings. (See Fig. 27.) The star-wheel upon receiving one impulse moves until an opening in same is opposite the air-pipe. This allows air to freely pass through the valve and out the other side, Fig. 12. In this position it remains during a blowing of plastic glass. When the glass is blown, the star-wheel receives a second impulse. This impulse closes the valve by bringing the solid part thereof opposite the inlet air-supply. There is one upright shaft 54 at each end of the machine, properly located to perform its proper operation.
- the commutator 2 is a metal case and surrounds the pipe 7. (See Figs. 34 and 35.) This commutator-case remains at rest and the pipe 7 revolves inside of same at one-eighth of a revolution to an impulse or one revolution for each cycle of the machine.
- Electric wires 103 and 104 extend from some external source of energy through the coupling 3 and flexible pipe 4 into the said commutator 2, where they are connected to springs 100, bearing the commutator metal brushes 102.
- the commutator is built upon an iron or metal bushing, upon which bushing is located the insulating fiber bushing 101. Upon this fiber are the rings of metal 99 99, whereby the metal rings are insulated from each other and from the metal bushing.
- the conductor-wires 103 and 104 then pass from the said rings into the pipe 7 and thence through pipes X to the motor V and rheostat W by a division.
- the entire duty of this commutator is to convey the electric current through the pipe 7 to the motors on the motor-cars without becoming twisted. Thisarrangementinsuresapositive electric connection to the motor-car at all times, giving one polarity of current to the motor. It will be noticed that but two wires enter the commutator and leave the same; but where the wires emerge from the flexible air-pipe there are four wires, owing to the division above referred to.
- Fig. 1, 8 shows the glass bulb when first l put into the machine, before the slickers have closed upon the same and before air from the machine has been supplied.
- Fig. 2 On the base A, Fig. 2, is shown attached to one side upon an upright supporting-shaft 124 by a swivel-joint 125 and clamp 126 a liexible pipe 128, bringing air from some extraneous supply to the Vicinity of the trav ersing slickers to cool the glass at the proper stage.
- This air-blast can be shut off and turned on by a valve similar to one applied on the motor-car at Valve 49, or it may be left on all the time, as it can be directed upon the glass only when the latter has reached the proper stage of the process and the proper position on the machine as the slicker-car passes through that part of its cycle.
- This air-pipe or air-blast may be one pipe or a collection of air-pipes for this purpose.
- the armature of the motorN is then again started by the hand regulating and starting rheostat 17, the radius-arm of which is set at such position as will snit the work in hand, different speeds being required for dierent-sized work.
- the motor N also brings into operation lthe rotary pump O, which supplies Water continuously to the top tank M.
- This starting of the armature of motor V has, through its connections of gearing and shafts and sprocket-chains through shaft G3, gear w, and circular rack at, started the slickers into revolution around the gathering of plastic glass S on blow-iron T.
- the blow-iron has started to revolve slowly in the opposite direction, the speed of both increasing as the process proceeds.
- the valve 49 has now opened, admitting air under full pressure to the motor-car E; but as the escape-valve 37 is still open but a slight amount of pressure is experienced at the plastic glass.
- the speed increases according to predetermined plan.
- the air-pressure increases according to predetermined plan, both governed by the camtracks L and K.
- the slickers open gradually, according to plan, as governed by camtrack I, Fig.
- the face of the slicker where it comes in contact with the glass is not necessarily of the same arc of curvature as the finished product.
- the edges or carriers of this face of the slicker are preferably rounded where they are presented to the plastic glass.
- the process of forming or slicking the glass article into shape commences.
- the slickers as soon as the plastic glass comes into contact with them commence to expand or open, and the expanding glass follows the opening slickers till the article has reached its desired final shape.
- the slickers remain a very short time in this position when the air-blast has reached the full pressure required for the article in process, after which it is turned off automatically.
- I can revolve the slickers about the plastic glass and have the blow-iron remain stationary with its gathering of plastic glass, or I can revolve the blow-iron with its gathering of plastic glass and also revolve the slickers about the yplastic glass in conjunction, as the case may require, in opposite directions or at differential speeds in the same direction.
- the design also economizes room around the glass-furnace, the machine being narrow and long. This is an advantage, as when two adjoining pots in a glass-furnace are worked they can be Worked with less interference in case ot a narrow and long machine, reaching away from the furnace.
- Each car or set of cars-a top and bottomv one Working in pairs-perform their operation separately from the other pairs, and by this method of construction a machine is capable of being greatly multiplied in capacity by the addition of pairs of cars. Pairs of cars in this type of machine can be worked on different forms or shapes, if desired, simply by having different sets of slickers for such shapes upon that pair of cars.
- slickers wherever used relates to static fingers or modelers, which operate on the plastic glass by, a rubbing or sliding action in contradistinction to revoluble formers, which operate on the glass by a rolling'action, on the one hand, or to sectional molds, which inclose the plastic glass and form its shape by compression at all points thereof. It is true that the glass is sometimes rotated in contact with the inner surface of such molds; but it is not modeled to form solely by rubbing contact, as is the case with slickers which nowhere inclose the plastic glass entirely, but leave room on all sides for the accession of cooling blasts of air between said slickers or fingers as the glass rotates in contact with them.
- a plurality of slickers for operating on plastic glass, in combination with means for supporting and rotating a mass of plastic glass in simultaneous sliding contact with said slickers, substantially as speciiied.

GLASS-WORKING MACHINE.
SPECIFICATION foriing part Of Letters Patent No. 620,642, dated March '7, 1899. Application led April 27, 1898. Serial No. 679,003. (No modeli) T0 all wiz/0m it may conce/"n:
Beit known that I, IRvINGW. CoLBURN, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Glass-Working Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to a novel means or apparatus for forming and manufacturing articles of glass, such as have heretofore been made by blowing in connection with sectional molds, either purely by manual process or in conjunction with machinery. By my present means I dispense with molds and form the article by means of slickers, ngers, or modelers, by which the plastic glass 'is ironed, kneaded, and modeled into shape as it revolves in contact with said slickers or fingers or as the latter are revolved around the plastic glass, or both in conjunction. The action thus differs radically from that which takes place when Sectional molds are employed, as in the prior practice of machine glass-working, with the advantage of the avoidance of fins, striae, and wrinkles on the surface of the glass, due to contraction in contact with a metallic chill-surface, and torsion strains and cleavage-lines in the glass, along which fracture is liable to occur in articles produced by the old method. Owing to the kneading and modeling action of the fingers or slickers larger articles than hitherto practicable by machinery may be executed and by means of labor of only ordinary skill in contrast with the highly-skilled labor hitherto found indispensable.
In the drawings forming a part of this specification, Figure 1 is a side elevation of the machine, partly in section. Fig. 2 is an end elevation of the machine, partly in section. Fig. 3 is an end section of top frame of the machine, showing the tracks on which the upper car-wheels run, also the cam-tracks on which the flange-wheels run which operate the rheostat, the air-discharge-regulating valve, and the device which lifts the air or blow-iron spindle.

Like letters and numerals of reference indicate like parts on the several drawings.
Referring to the drawings, A represents the base partor bottom frame of the machine. The base A is the frame upon which all the machine is assembled.
B is the top part or frame-plane, supported on base A by columns (l C. On base A are two upright bosses or extended hubs 115, into which are inserted and preferably screwed the said columns. These columns are made in two pieces C C C C2, with couplings 1/1 made fast to columns C at 13. The upper portions C' C2of said columns have screw-threads cut on them at 12 and hand-wheels Y' Y2, screw-threaded inside, fitting the same to provide for raising or lowering the top part or frame-plane B to accommodate different kinds of work in process in the machine. Y The base A (see Fig. 5) has three tracks running around the same. Two, H H, are level tracks, on which run the car-wheels of cars F. The middle track or cam-track I is of varying height,according to the duty that it is expected to perform. This cam-track is preferably formed of light bar iron or steel and made removable and adjustable, so that it can be easily changed and a different one putin its place. Said track is held in position with suitable lneans for adjustment, and the variations of level are fashioned in accordance with the Work in hand. In the lower part of the base A is the well 31 for holding water, having a shelf 75, on which the pump O is placed for pumpingwater to the tank M on top of the machine.
Q is a long metal housing supported on base A. In this housing the slickers get a most complete wetting and cooling, and whatever water falls outside the main water-basin or between the tracks at once finds its way back to the tank 31. There are holes or passages 32, Figs. 1 and 4, under the tracks H H to accommodate the return of such water.
vThe object of the housing Q, above referred to, is to prevent water from escaping outside the machine while wetting and cooling the slickers. In this housing are located the sprinkling-pipes 33, the water to same coming from the tankM on top of the machine through pipe 34. The supply is controlled by valve 41 as to quantity and may be shut off entirely, if desired. There is a suction-pipe 3G connected to the pump O. From pump O the supply passes through pipe 35 to top tank M. The pump is operated from the motor N by endless belt 15. In case of any surplus water accumulating in top tank M the same is returned to well 31 through overflow-pipe 117.
The base A is supported for convenience of moving on truck-wheels 29 30, wheel 29 being the steering-wheel. There is a'provision for locomotion, which will be described later. On said base A are also mounted the boxes 114 1111, in which run the vertical rotary shafts D' D2. Shaft D2 derives rotary motion from a motorN on bracket 18, borne on column C to the right. This motor, preferably electric, derives its motion from an outside source of electric energy, the wires from which (not shown) enter at a fuse-block or 'cut-out 38 on the side of the machine, Fig. 2, preferably inclosed in the form. of an insulated exible cable. From this cut-out the wires pass under the machine, thence up inside the column C at therear of the machine, which has a pas- Sage provided for the purpose, and thence to the motor N. A branch'of the circuit which energizes the armature leads through the rheostat 17, the function of which is to govern the starting, stopping, and controlling of the current. ASaid motor communicates its motion to shaft D2 through train of gears 16, Shafts D D2 are connected together by means of endless ropes, belts,'chains, or wire cables 82 69, passing around flanged pulleys P P', and rotate together at equal speeds. At the foot of shaftD2 is a bevel-pinion 21,intermesh ing with bevel-gears 22 23 on the shaft of truckwheels 30. These bevel-gears are mounted with a spline, so as to have longitudinal motion on the shaft, and are controlled by a le-A ver 19, pivoted at 20, carrying rings 133, which engagegrooved collars 132 on the said bevel-gears, by which means the gears can be shifted to the right orleft, as desired. -The object is to give locomotion to the machine in any direction by power derived from the electric motor N.
As shown in Fig. 23, the handle 19 is in a perpendicular position, in which position the gears 22, 23, and 21 are not in mesh. By moving this handle or lever 19 to the left gears 21 and 22 engage andthe machine takes motion and travels slowly on the floor. By moving the handle the other way the gears 21 and 23 mesh and the machine takes motion in the opposite direction. The machine is governed by means of the hand-wheel 25, thev shaft 27, and the train of gearing 2S 2S 2S, controlling the hoor-wheel 29. The Inovement is slow and readily under control. The
direction back or forward is controlled bythe lever 19, the direction to the right or left by IOO hand-wheel 25, and the speed ofthe machine about the floor is regulated by the rheos'tat 17, which governs the speed of the motor N.
When the machine is in its position in front of a glass-pot in the furnace, the duty of the motor N is to operate the shaft D2, as above described, and this shaft communicates motion and power to the shaft D by means of the wire ropes or cables illustrated at 69 and 82. These wire ropes or cables have also the duty of carrying around the frame of the machine pairs of cars-viz., the motor-car E on the top frame and the slicker-car F on the bottom frame. These cars are attached to the cable as follows: The car F is held with clamp 74, Fig. S, and has lingers or steadyingarms S4, which when the car is on the straightway part of its course come into contact with the cable and prevent vibrations which might occur from any hitching along the track. Similar lingers may be applied to the top motor-car and are in practice, but they are not shown in the drawings. The cable-wheel P has parts cut away in same at 85, which permits the clamps which hold the motor and slicker cars to pass around the wheel smoothly. it also provides for the take-up coupling 2l and the knocker or striker clamps 97 to pass in the same manner. The Jrop cable-wheels and lower ones are of similar'construction and have like duties to perform, with the eX- oeption of the striker-clamps.
On the tracks H on base A run the slickercars. (Shown in detail on Sheet 4, Figs. 7 and 8.) These cars consist of a base portion F, mounted on truck-wheels 83, with means 74 for clamping the same to cable 82, and an upper portion F', supported on the base portion by means of ball-bearings S9 on a circular trackway, so as to rotate freely by means hereinafter to be described. This upper portion carries the slickers G, radially arranged, so as to have free, radial movement toward and from the center, while the upper portion F', which carries them, is rotating. The outward movement of the slickers is accomplished by means of cone tnbearing against rollers 86, attached to the slickers. Cone a is operated by means of the adjustable and exchangeable cam-track I, whose upper edge is of varying height, in accordance with the work required of it.. This cam-track Iraises and lowers the liange-wheel t running on the same. Said wheel is borne ina hanger, on top of which is spindle 87, which turns loosely in the stem of the cone u and takes end' thrust upon ball-bearings 90. As the slickers revolve around the plastic glass this wheel remains stationary, simply traveling around with the machine on the cam-track I and lifting and lowering the cone it in accordance with the rises and falls in the camtrack l. The lifting of the cone upushes back the rolls So', which are attached to the slicker-supports y y y. These slicker-supports y have slots 121 formed in same, which guide the said supports as they advance or retreat from the glass. The slickers maybe of metal or any other material which will stand the temperature and friction. They are held up to the plastic glass by the springs 7 6, and
the regulation of the advance and retreat is y governed by the formation of the cam-track I. The slickers G are slotted at 77 as a means of adjustment and held invposition by screw and washer 7 3.
The slickers are of the shape illustrated in Figs. 15 to 18, inclusive, Sheet 3, and are preferably rounded at their edges, as shown in Fig. 16, and their duty is to slick, smooth, model, or iron the plastic glass into the required shape as they come in contact therewith. In practice they are preferably pastecovered on their contact-faces.
The slickers shown in Figs. 21 and 22 are designed for forming the bottom of a glass article, as shown at 94. They can be of any shape in the reverse that is desired to be imparted to the article of plastic glass in process of formation. This slicker is held in position by arms 93 centrally beneath the rotating slickers. Figs. 19 and 2O represent a means for making the same set of slickers fashion and shape the plastic glass at bottom as well as at the sides, but is adapted only for plain-bottom or straight-bottom glasswork.
The frame-plane B also bears trackways f f,on which run the upper motor-cars E. These cars are impelled by the same power and at the same speed as bottom cars F by means of cable 69, driven from shaft D2 and passing over pulleys P. The said cars are connected to said cable by means of connecting-arms q and clamps h. They are thus designed to move synchronously with the bottom cars F and remain directly over the same. Between each top and bottom car extends the vertical connecting -rod 122, firmly attached to each car at the sides. arms 113, having at the extremities thereof the blow-iron supports or bearings U U for sustaining the blow-iron T in a vertical position during the entire circuit of the cars. This bearing U, Fig. 31, is cone-shaped, so as to retain the blow-iron, which has a reverseshaped cone, on same. Said bearing U has an insertible composition piece or bushing 96 for renewal in case of wear. This serves to keep the blow-iron in position and for a bearing. There are two for each pair of cars, as shown in Fig. 1. Figs. 30 and 30a represent a method of constructing the end of the blow-iron so as to lit the clutch for driving the same by means of cross-pins 131. This admits of no difficulty in positively catching the spindle and driving the blow-iron. In the air-spindle is a clutch fr. This clutch has the proper shape to engage with the blow-iron. There is a ileXible washer 42 in the bottom of air-spindle clutch, which makes the blow-iron contact with the clutch air-tight.
The blow-irons T are removable, insertible, and hollow and bear on their lower ends the bulb of plastic glass to be modeled by the This rod carries horizontal IOO IIO

slickers during the cycle of operation. This blow-iron receives rotary motion and a supply of air for expanding the glass bulb bymeans presently to be described. There also extends from the upper to the lower car the vertical rotary shaft 63, whose office i-t is to impart rotary motion to the revoluble member of the slicker-car F by means of gear-wheel w', meshing into circular rack a; on the periphery of revoluble member FC The shaft 63 is run in trunnion-supported boxes S8, attached to both top and bottom cars, so as to be preserved at all times in alinement. It is supported upon ball-bearings.
Besides the car-tracks f there are borne on the upper frame-plane B three adjustable and exchangeable cam-tracks J, K, and L, whose functions are similar to those of cam-track I on base-frame A. These cam-tracks have their upper edges formed of varying heights, in conformity with the functions which they have to perform. The function of cam-track J is to automatically regulate the degree and time of the rising and falling of the blow-iron spindle p, which communicates with the vertical blow-iron T and supplies rotarymotion and air thereto. The function of the camtrack K is to automatically regulate the airpressure of the air-supply furnished to the said spindle, and the function of the camtrack L is to automatically control the rheostat-arm of the rheostat l/V, which regulates the amount of current supplied to the armature of the electric motor V. The said motor V, blow-iron spindle p, and rheostat WV'are all carried on theupper motor-car. The blowiron spindle receives its supply of air from an external source presently to be described. The said spindle receives its rotary motion from motor V, gears n and lo, shaft 63, and sprocket -Wheels m and Z.V The spindle is splined in the sprocket-wheel Z, so as to admit of rising-and-falling motion while rotating, and said sprocket-wheel Z is confined by a collar 73 and groove 72 from following the rising movement of the spindle. First, as to camtrack L, the armature of the motor V is supplied with current from an external source through the rheostat W. The field-magnets of the inotor are supplied with a constant current and remain at all times charged while the The rheostat lV, when the motor-car arrives at the place where the glass is to be put into the machine, automatically turns on a limited supply of current to armature, thus at once starting the machine gradually under automatic regulated speed by means of the cam-track L and flangewheel 57, increasing the speed of the motor until the operation is completed, at which time the wheel 57 drops and the current is shut off from the motor-armature until next cycle is started upon. Second, as to cam-track K, on which runs the flange-wheel j. The duty of this cam-track and wheel is to admit of a discharge of air from an air-box 46, borne on the motor-car E. This air-box 4G receives its supply of air through a flexible pipe X and -air-pipe o, with a little surplus capacity for carrying air over what is actually required for the largest work to be done with the machine. The diameter of the flexible air-pipe X and pipe o determines the carrying capacity in air. From this air-box 4G the air has two paths open to it, one through chamber 46 to chamber 45 in column 61 'through the cross-holes 44 in blow-'iron airspindle to central passage 43 in center of blow-iron air-spindle, thence to plastic glass. Were it not for the escape air-valve 37 too much air-pressure would at once be applied to the delicate plastic glass. Therefore this air-escape valve 37 is provided. Vhen air is admitted to the air-box 46 through the valve 49 at top of air-pipe o, the spindle is in the air-box, exposing its opening 47 to the incoming air, offering a free second path for same through this spindle to the outlet-slot 48. As the work of forming the plastic glass commences, but very little air-pressure passes to the inside of the plastic glass, as the escape air-valve 37 is keeping this pressure down. As the forming of plastic glass proceeds in the car below, this valve-spindle 37 gradually or otherwise, if desired, descends by the aotion of cam-track K and roller j, thus decreasing the size of the discharge-opening into this spindle until the air-passage is shut od entirely or to the extent desired as the required pressure may demand, depending upon the work in hand. This method of regulating air-pressure is positive and is capable of giving puffs or impulses, sudden or gradually increasing, as the case may require, by simply having the cam-track arranged accordingly. It can closely imitate the pressure given by a skilled glass-blower when operating difficult work, blowing same by lungpressure. This enables the air-pressure to be governed absolutely according to the work that is to be done with the machine. Thirdly, as to cam-track at J. The duty of this camtracl; is to operate the lifting and lowering IIO of the blow-iron spindle, as beforesaid. The
from the machine.
On base A is also borne the hub or boss 118, in which is journaled the central shaft R, passing up through the frame-plane B. This shaft is solid throughout its entire length and has ball-bearings for end-thrust at 119. At its top is the air-box l, carrying the extended flexible pipe X X, one for each car. Into the top of the said air-box and in axial alinement with the rotary shaft R extends the vertical rotary air-pipe 7, communicating with the air-pipe 4, which may be flexible, leading to an external source of airsupply under pressure. 2 is a commutator, presently to be described, forming the connection between the rotary air-pipe 7 and the stationary air-supply pipe 4. The shaft Ris stationary most of the time, but receiving periodical impulses. In the present machine it is arranged to give this shaft eight impulses for each operation or during one complete cycle of the cars. This is accomplished by the knockers 9.7, Fig. 26, striking against the extended arms 9S, by which each time they come in contact they advance the wheel one-eighth of a revolution. The object of this operation is to at all times have the flexible air-pipe X approximately in line with the motor-car E. The duty of this flexible pipe is to convey air under pressure to the motorcar from air-supply pipe 4, and also to carry electric wires to the motor on said cars by the interposition of the commutator 2, without which or some similar device the air-pipes and electric wires would become entangled while the machine was making one cycle. This plan admits of air being supplied to the cars under the same pressure at all times, at the same time carryingthe wires tothe moving cars without any danger of breakage or strain. The flexible pipes pass over a round elbow e, thereby preventing any sharp bends in them,whetherthey are in the position shown in Fig. 1 or Fig. 2. care lever-arms attached to the flexible air-pipes by means of links b and elbows e. These lever-arms are always kept taut through the tension-springs d, thus at all times keeping the air-pipes in position and preventing wear or abrasion. The airpipe X communicates with vertical air-pipe o on the motor-car and supplies air to valve 49, Figs. 27 and 28. The duty of this airvalve is to open as soon as the plastic glass is put into the machine and to close upon the operation being completed. This is accomplished through the striker-pin 52, which is adjustable upon the npr-ight shaft 54. This striker-pin engages with the star-wheel 51 on the air-valve shaft. This starwheel has eight arms. The air-valve has four openings. (See Fig. 27.) The star-wheel upon receiving one impulse moves until an opening in same is opposite the air-pipe. This allows air to freely pass through the valve and out the other side, Fig. 12. In this position it remains during a blowing of plastic glass. When the glass is blown, the star-wheel receives a second impulse. This impulse closes the valve by bringing the solid part thereof opposite the inlet air-supply. There is one upright shaft 54 at each end of the machine, properly located to perform its proper operation.
58 shows the flange-wheel for lifting the blow-iron spindle by means of the cam-track J, on which it runs. This wheel is held with bearing or collar 59 on blow-iron'spindle. It is held in position on the shaft from moving lengthwise by the two collars 60, which are attached to the spindle with screws, and has ball-bearin gs for end thrust to lessen friction.
The commutator 2 is a metal case and surrounds the pipe 7. (See Figs. 34 and 35.) This commutator-case remains at rest and the pipe 7 revolves inside of same at one-eighth of a revolution to an impulse or one revolution for each cycle of the machine. Electric wires 103 and 104 extend from some external source of energy through the coupling 3 and flexible pipe 4 into the said commutator 2, where they are connected to springs 100, bearing the commutator metal brushes 102. The commutator is built upon an iron or metal bushing, upon which bushing is located the insulating fiber bushing 101. Upon this fiber are the rings of metal 99 99, whereby the metal rings are insulated from each other and from the metal bushing. The conductor- wires 103 and 104 then pass from the said rings into the pipe 7 and thence through pipes X to the motor V and rheostat W by a division. The entire duty of this commutator is to convey the electric current through the pipe 7 to the motors on the motor-cars without becoming twisted. Thisarrangementinsuresapositive electric connection to the motor-car at all times, giving one polarity of current to the motor. It will be noticed that but two wires enter the commutator and leave the same; but where the wires emerge from the flexible air-pipe there are four wires, owing to the division above referred to. This will not need further description, as it is the well-known way of taking two wires from any outside source of electric energy and connecting them so as to energize the field-magnets of the e1ectric motor and at the same time control the motor-armature with the rheostat.
As shown in the machine illustrated in the present drawings, four sets of cars can ordinarily be in operation at the same time; but the method is not limited to this number.

On the base A, Fig. 2, is shown attached to one side upon an upright supporting-shaft 124 by a swivel-joint 125 and clamp 126 a liexible pipe 128, bringing air from some extraneous supply to the Vicinity of the trav ersing slickers to cool the glass at the proper stage. This air-blast can be shut off and turned on by a valve similar to one applied on the motor-car at Valve 49, or it may be left on all the time, as it can be directed upon the glass only when the latter has reached the proper stage of the process and the proper position on the machine as the slicker-car passes through that part of its cycle. This air-pipe or air-blast may be one pipe or a collection of air-pipes for this purpose.
Operation of the machine: Taking the machine when at a state of rest I will describe the starting of the machine and the completion of one cycle of operation of one pair of motor and slicker cars. The operation is duplicated in the other pairs of cars. First the machine has been brought to its position in front of the furnace through the motor N, the train of gearing 1G, the shaft D2, bevel- gears 21, 22, and 23, and the guiding device on front of the machine, consisting of hand-wheel 25, shaft 27, train of gearing 28, and steeringwheel 29. After the machine is duly placed the handle 19 is returned to perpendicular position. The armature of the motorNis then again started by the hand regulating and starting rheostat 17, the radius-arm of which is set at such position as will snit the work in hand, different speeds being required for dierent-sized work. This starts the cars into movement through shafts D2 D and cables 69 82, their speed around the machine on their respective tracks being governed by the set of the rheostat-arm. After the speed is once set it remains constant. The motor N also brings into operation lthe rotary pump O, which supplies Water continuously to the top tank M. These operations being all initiated we will suppose that a pair of cars, both motor and slicker, have arrived at the position shown at the extreme left, Fig. 1. At this position the slickers G are at their widest opening apart. The air is shut off from the upper car by air-valve 49 at end of flexible cable X. The blow-iron spindle, with the clutch, is lifted to its highest position. The lever 56 of the rheostat W is at the position Where the current is entirely shut oif, and the motor is at rest. The air-discharge pressurevalve is at its highest position ready to take air freely and give a free second path for air from rair-chamber 46, thus admitting air at low pressure to blow-iron T when it comes on. The operator has now just putin a fresh blowiron with its fresh gathering of plastic glass thereon into the blow-iron supports or bearings U, with the glass between the slickers. This gathering of glass has first received the slight hand and lung manipulation required of same before being put into the machine. But a slight amount of skill is required to do this. Immediately the slickers close upon the bulb until they come in contact therewith. While this is being done various other movements are taking place on the upper or motor car. The blow-iron clutch has meantime descended into contact with the blow-iron, sealing same air-tight by means of the flexible washer 42 in clutch 7'. (Shown in Fig. 12.) The motor V on the top car has now started slightly, the rheostat arm 5G having' been moved by the operation of cam-track L. This starting of the armature of motor V has, through its connections of gearing and shafts and sprocket-chains through shaft G3, gear w, and circular rack at, started the slickers into revolution around the gathering of plastic glass S on blow-iron T. The blow-iron has started to revolve slowly in the opposite direction, the speed of both increasing as the process proceeds. The valve 49 has now opened, admitting air under full pressure to the motor-car E; but as the escape-valve 37 is still open but a slight amount of pressure is experienced at the plastic glass. The speed increases according to predetermined plan. The air-pressure increases according to predetermined plan, both governed by the camtracks L and K. The slickers open gradually, according to plan, as governed by camtrack I, Fig. 7, andthe plastic glass has gradually expanded as the slickers have opened until the glass has attained its correct size and approximate iinal shape. At this time the slickers will remain in this position for awhile until the speed has increased in the motor to its desired limit, all thewhile revolving the slickers in contact with the revolving article of plastic glass,whic h now has taken its final shape, being modeled into perfect contour by the revolving paste-covered slickers and smoothed and ironed and slicked until all creases are out of the same. t The air-pressure has increased to the limit required for this operation and the air from outside pipe 128 commences to come into contact I motor, thus stopping the motion of the same and with it the revolution of the blow-iron spindle and the slickers. The clutch lifts o from the blow-iron. The air-valve 49 closes, shutting off the supply of air from this motorcar. The air-regulatin g escape spindle-valve 37 lifts, ready for a second operation. The glass article is taken from the machine and the slicker-car advances into the metal housing Q,where the sprinklers are at work throwing a liberal supply of water upon the slickers, which now entirely floods them, wetting their paste-covered surfaces and cooling them thoroughly. Vhen they come from out the housing, they are entirely cool and ready for another cycle of o peration.
The pair of cars now goes throughv IZO The operation of one pair of cars is duplicated in the others, the several operations taking place at Vthe same time on different pairs of cars.
The face of the slicker where it comes in contact with the glass is not necessarily of the same arc of curvature as the finished product. The edges or carriers of this face of the slicker are preferably rounded where they are presented to the plastic glass. By this means the plastic-glass article is kneaded, ironed, modeled, smoothed, and slicked into its ultimate shape. This operation is one not possible to be practiced with the sectional mold. In my machine as soon as the bulb of glass has been taken from the furnace, manipulated slightly, and placed in the machine and the machine is started the slickers at once approach each other until they have embraced the plasticglass bulb on all sides. Immediately the regulated air-blast is admitted and the process of forming or slicking the glass article into shape commences. The slickers as soon as the plastic glass comes into contact with them commence to expand or open, and the expanding glass follows the opening slickers till the article has reached its desired final shape. At this stage the slickers remain a very short time in this position when the air-blast has reached the full pressure required for the article in process, after which it is turned off automatically. During the time that the slickers are expanded to the finished size of the glass article in process the outside air-blast from an external source of air-supply is turned onto the slichers and also the finished product, as before mentioned, which it can readily reach through the spaces or openings between the sides of the slickers, and thus materially assist in cooling the finished product prior to being taken from the machine. As soon as the operation on the plastic glass has been completed the slickers expand to their fullest extent, which gives ample room to remove the finished product. They are then wet and cooled in the sprinkling-house and are ready for a fresh gathering of plastic glass.
At no time during the various contractions and expansions of the slickers do they touch each other. IVhen they first embrace the plastic bulb before the process of expansion takes place, they are very close together, but not in contact.
There are very few articles, such as very small and thick ware, that can be made nearly as well by dispensing with the expansive properties of the slickers. In such cases the slickers can then upon approaching simply close to the exact size ofthe finished product, remaining there until the article is slicked into shape, and then expand to remove the product. All these movements can be regulated to a nicety by means of the long camtrack I, which admits of any adjustment.
In almost all kinds of work the product is much bettered by beginning the modeling the finished product at the other end.
from the first expansion of the plastic glass, asI am enabled to do with this method of employing expansion-sliclers. Abrupt irregularities in the finished glass product, such as sharp angles and curves, can be much better Worked by beginning to make the glass take its final shape at first, when the bulb is small and very plastic, and causing the expansion to follow the lines of the slickers from there on.
As soon as glass has taken its shape the space between the slickers admits of air getling to the product, and during the last of the operation, when the article is nearly completed, this space between the slickers is sufficient for the air cooling preparatory to taking the product from the machine. This cooling the finished product by air-blast materially aids the machine in increasing its capacity for doing` work. It hardens and cools the glass somewhat, so that contact with any hard substance after being removed from the machine is much less liable to dent and injure it. In this invention I may revolve the blow-iron with its gathering of plastic glass and not have the slickers revolve about the plastic glass. I can revolve the slickers about the plastic glass and have the blow-iron remain stationary with its gathering of plastic glass, or I can revolve the blow-iron with its gathering of plastic glass and also revolve the slickers about the yplastic glass in conjunction, as the case may require, in opposite directions or at differential speeds in the same direction.
By providing that the slickers shall never come quite together under any circumstances in operation upon the plastic glass I avoid the common trouble in mold-machines of refuse glass from last operation getting between the edges of the mold, and thus spoiling that one operation and running the chance of injuring the mold and machine. I do not limit myself in any manner to applying this invention to the style of frame illustrated in this application, since these slickers are applicable to almost any other type of glass-blowing machines, including those using sectional molds, and will do better Workin larger pieces and at the same time more rapidly than is now accomplished With the common sectional mold. This feature can readily be applied to other types of machines by the substitution of the slicker mechanism.
In the type of frame that I illustrate with this machine I obtain many advantages, a few of which I will mention.. The machine being a straightway one, the operators that attend or feed it are at one end. They have free access to that part of the machine without interference from the tenders, Who remove Immediately upon the glass being put into the machine it begins its retreat from the furnace, continuing to retreat until final removal from the machine. This feature of putting plastic glass in at one end and removing the finished product from the other also adds to IOO IOS
IIO
the capacity of product that such a machine is capable of, as the tenders each have room for their respective operations uninterfered with. The design also economizes room around the glass-furnace, the machine being narrow and long. This is an advantage, as when two adjoining pots in a glass-furnace are worked they can be Worked with less interference in case ot a narrow and long machine, reaching away from the furnace.
Each car or set of cars-a top and bottomv one Working in pairs-perform their operation separately from the other pairs, and by this method of construction a machine is capable of being greatly multiplied in capacity by the addition of pairs of cars. Pairs of cars in this type of machine can be worked on different forms or shapes, if desired, simply by having different sets of slickers for such shapes upon that pair of cars.
It is also a great advantage to make use of the main motor for the purpose of converting the machine temporarily into an electric car by throwing the power-shaftinto contact with the truck-wheels by means of bevel-gears, and thus being enabled to move the car or machine from one position to another about the furnace to whichever glass-pot is to be drawn from. This in the past has been accomplished by manual labor, which in such large and heavy machines as glass-machines requires considerable force, which is economized by utilizing mechanical power under perfect control as to speed and direction.
Inthe foregoing description it is to be understood that the word slickers wherever used relates to static fingers or modelers, which operate on the plastic glass by, a rubbing or sliding action in contradistinction to revoluble formers, which operate on the glass by a rolling'action, on the one hand, or to sectional molds, which inclose the plastic glass and form its shape by compression at all points thereof. It is true that the glass is sometimes rotated in contact with the inner surface of such molds; but it is not modeled to form solely by rubbing contact, as is the case with slickers which nowhere inclose the plastic glass entirely, but leave room on all sides for the accession of cooling blasts of air between said slickers or fingers as the glass rotates in contact with them. This is the radical distinction between molds and slickers. v Said slickers or iingers, while static in their operation in the sense that that they do not revolve on axes of their own, like the revoluble formers before referred to, may revolve as a group in place of revolving the plastic glass; but this does not make the term revoluble applicable to them as slickers.
